      Description

      If we run data node and region server in the same physical machine, region server will be benefit if the store files for its serving regions have a local replica in the data node process.

      So for each regions, there exists a best locality region server which has most local blocks for this region.
      The HBase Locality Checker will show how many regions is running on its best locality region server.
      The higher the number is, the more performance benefits HBase can get from data locality.

      Also there would be a followup task to use these region locality information for region assignment. Assignment manager will prefer assign regions to its best locality region server.

          Is the followup task covered by HBASE-4191 ?

          Good utility. Looking forward to it.
